I am using a painless harness for my 40. I am in the middle of wiring it. I have ordered a single throw - double pole switch for the hazard switch. There will be 2 outputs on the hazard switch and they will connect to the left and right turn circuits. In the off-position, they are separate, so the turn signals will work correctly, but in the on-position, both left and right will flash.
